How Can I Detect Browser Tab Activity Using JavaScript?

Browser/Tab Activity Detection [Duplicate]

In the realm of JavaScript, it's often desirable to only execute code when the current page is actively visible to the user. This is a common scenario for CPU-intensive operations that are unnecessary to perform while the browser or tab is in the background.

To address this, the Page Visibility API provides a reliable solution. The document.hidden property indicates whether the page is hidden from view (such as when the browser is minimized or another tab is active):

if (!document.hidden) {
    // Do what you need
}

In addition, here are some notable resources for further understanding:
